Inside of the update function, set a variable named instance to the old_instance parameter. Then use the strip_tags function to sanitize the title of the new_instance and assign it as the title of the instance variable. Below that return the instance variable.

plugin.php 
<?php

    class My_Plugin_Widget extends WP_Widget {

        function my_plugin_widget() {
            parent::__construct( false, 'My Plugin Widget' );
        }
    function widget( $args, $instance ) {

    }
    function update( $new_instance, $old_instance ) {

      $instance = return( $new_instance, $old_instance );
      $instance['title'] = strip_tags($new_instance['title']);

    }
    function form( $instance ) {

      $title = esc_attr($instance['title']);

      require( 'inc/widget-fields.php' );
    }


    }
